CXLE87141 is a single-line three channel LED constant current driver special circuit It can switch input with each other through dual channel digital interface and cascade with DO port

CXLE87141 is a single-line three channel LED constant current driver special circuit. It can switch input with each other through dual channel digital interface (DIN, FDIN) and cascade with DO port. The external controller only needs one line to control the chip. The chip is integrated with MCU single line dual channel digital interface, data latch, LED constant current drive, PWM brightness control and other circuits. The VDD pin is internally integrated with 5V regulator and few peripheral devices. This product has excellent performance and reliable quality.
